By the way, this is a pretty sweet program!
Thanks. But please don't use code from it in your own projects yet: Not all code is mine: I used some routines from other people of which most of them are modified to fit the needs of this program, And I want those people and everybody who helped me to to have some credits. And it'll probably be open source anyway when it's done.
please pm me a compiled version spasm doesnt work for me

Ok, I'll send you one
EDIT: I just thought that it might be best to put it on the tread itself, for anyone else who wants to run it when spasm doesn't work, so here's the link:
